Tissot's PRX Grendizer 50th Anniversary: A Cosmic Tribute To A Legendary Hero

Half a century after Go Nagai first created UFO Robot Grendizer in 1975, today, Tissot brings the hero back to life in the form of the PRX Grendizer 50th Anniversary Special Edition. Limited to 1,975 pieces, this watch is both a celebration and a reunion a return of a starborn warrior who has traveled through time and memory to inspire once again. Following the success of the first PRX Grendizer edition in 2024, the legend blazes back like a comet, carrying with it nostalgia, imagination, and innovation.

As Grendizer celebrates 50 years of legacy, this watch becomes more than just a timepiece. For anime fans and dreamers alike, it is a reminder that some heroes transcend generations crossing space, time, and culture to keep sparking wonder in us all.

Darkness, Made to Shine
Dressed in a full black PVD-coated case, the PRX embodies the strength and mythic energy of Grendizer himself, the lone defender from the stars. Its signature bracelet reinforces that story: built for endurance, protection, and brilliance even in the darkest skies. Retro-futuristic in design, it blends the spirit of vintage anime with the precision of Swiss watchmaking savoir-faire.

The dial becomes Grendizer’s stage, where he strikes a dynamic pose with his fist angled forward, as though breaking through the sapphire crystal. Sculpted details and layered textures give him lifelike presence, while glowing yellow eyes and Super-LumiNova accents allow him to shine after dark like a cosmic beacon. Cutting across this galactic canvas is the seconds hand, shaped like the Double Harken and rendered in 18K gold an emblem of his unstoppable power.

Engine of the Starborn
Powering this stellar edition is the Powermatic 80, offering an 80-hour power reserve and equipped with a Nivachron balance spring to resist magnetic fields and temperature shifts. Water-resistant to 10 bar, it is a movement as resilient as Grendizer himself, engineered for adventures both earthly and beyond.

Turn the watch over, and the transparent caseback reveals another secret: Grendizer engraved on the oscillating weight, watching over the mechanism like a silent guardian. Each piece carries its own number, with the caseback marked “Limited Edition 1 of 1975” a direct homage to the year this legendary hero first lit up TV screens.

A Portal to Childhood
Created in collaboration with Go Nagai, the PRX Grendizer 50th Anniversary is more than a tribute, it is a time capsule of memories. The watch is presented in a Spazer UFO-inspired capsule, resting inside a striking black-and-gold box. Within, collectors will find exclusive drawings crafted for this edition and personally signed by Nagai, making every unboxing an event of its own.

Every detail resonates with nostalgia, transporting wearers back to the first time they witnessed Grendizer’s story. While time may never let us return to that exact moment, opening this box feels like stepping into a portal one that rekindles the same childlike wonder, proving that some heroes truly never fade.
